Title: Rubber mold composition for vacuum cast molding
Inventor: IWAMI FUMIO
IPC: C08L77/10
Filed: 1986-01-28
Abstract: PURPOSE:To drastically improve the dimensional accuracy and durability of a molded part and at the same time strikingly reduce its cost by a method wherein a specified amount of polyamide fiber is added to specified polysiloxane. CONSTITUTION:From 0.3 to 5 parts by weight of chopped aromatic polyamide fiber 10-15mum in diameter and 1-6mm in length are added to 100 parts by weight of dimethyl polysiloxane with a viscosity of 800-2,500 poise. If the amount of the chopped aromatic polyamide fiber added to 100 parts by weight of the dimethyl polysiloxane is below 0.3 parts by weight, no reinforcing effect is obtained, while if said amount exceeds 5 parts by weight, the viscosity of mixture becomes high and consequently the manufacture of a mold becomes extremely difficult. By the constitution as mentioned above, the characteristic of aromatic polyamide film are imparted to dimethyl polysiloxane while keeping the original merits of dimethyl polysiloxane. Consequently, the improvement of maintainability of dimensional accuracy due to the improvement of the tear strength, the improvement of the resistance to chemicals or liquid resin such as urethane resin, epoxy resin or the like, the lowering of linear expansion coefficient and the improvement of hardness is realized.

Abstract: PURPOSE:To prevent the transmission of the movement of a cover to the original placed on a platen by using a material having resilience as a cushion to be attached to the bottom surface of a cover and providing a hollow part having a suitable shape. CONSTITUTION:Soft rubber is used as a mterial for a flat plate-shaped cushion 5 to be attached to the bottom surface of a cover 4, and a hollow part 6 is provided, to the bottom surface of which a white film 7 having high smoothness is adhered. When the cover 4 is put on the original 8 positioned and placed on a platen 9, the hollow part 6 is crushed by the weight of the cover 4 to press the original 8 via the film 7 onto the platen 9. The platen 9 in this state is moved in a forward direction. When the movement in a backward direction is started after turned-over, the cover 4 moves together with the platen 9 and is turned over. Even if a hinge clatters in this stage, the movement of the cover 4 is absorbed by the cushion 5 on the bottom surface thereof and the cover itself moves by as much as the cover clatters but the movement is not transmitted to the original 8 and the original 8 stays put in the place positioned by a positioning plate 10 without deviation.

Title: Production of standard sample of high-carbon iron steel for carbon analysis
Inventor: FURUTA SEISHI
IPC: G01N1/28
Filed: 1988-01-26
Abstract: PURPOSE:To prevent crystallization of graphite and to improve the reliability of an analysis by subjecting a molten steel contg. >=1.5wt.% C and consisting of the balance Fe to rapid pulverization by gas atomization. CONSTITUTION:The molten steel contg. >=1.5wt.% C and consisting of the balance Fe is subjected to the rapid pulverization by the gas atomization. Since the molten steel is pulverized at >=10 deg.C/sec cooling rate by the gas atomization method, the powder is cooled before the crystallization of the graphite is effected; therefore, the crystallization of the graphite is not observed at all. The crystallization of the graphite is thereby prevented and the reliability of the analysis is improved.
